Reaction Steps

The title compound was prepared in an analogous fashion to that described in Example 33 using 6-chloro-5-(1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazol-5-yl)-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 32.1) and tert-butyl 4,7-diazaspiro[2.5]octane-4-carboxylate to afford an amorphous white powder. HPLC (Condition 4) tR=4.17 min, UPLC-MS (Condition 3) tR=0.78 min, m/z=459.1 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 0.46-0.85 (m, 4H) 3.04 (br. s, 2H) 3.16-3.37 (m, 5H) 6.67 (br. s, 1H) 7.34 (d, J=8.60 Hz, 2H) 7.86 (d, J=9.38 Hz, 3H) 8.34 (br. s, 1H) 8.75 (s, 1H) 10.43 (s, 1H) 12.96-13.19 (m, 1H).
